Filther

Filther is an AudioUnit effect plugin that adds color and character to any sound. At its heart is an extremely steep -48 dB/octave low-pass filter with dual-stage waveshaping distortion. Modulated by an input envelope follower and an LFO that goes into audio range, this filter can do anything from deep low-end isolation, juicy wah-wah to growling sweeps and waveform sculpting – all from its intuitive, color-coded interface.
